Yamauchi No.10 Family Office

This is not your typical website. This website from the family office of Nintendo’s founder just brings back the 80s vibes.

It’s nothing short of amazing what you come up with when you’re not bounded by traditional constraints of what a website is supposed to look like.

We are Yamauchi-No.10 Family Office. Our mission is making a contribution to the society through our activities.

Troubleshoot Boot and Networking Issues with New EC2 Serial Console | AWS News Blog

This is extremely useful for those times when the system is unable to get to the stage where sshd is running, or there are network-related issues which prevent a normal ssh connection from working. This is akin to the console view of a VM through the hypervisor.

… EC2 Serial Console, a simple and secure way to troubleshoot boot and network connectivity issues by establishing a serial connection to your Amazon Elastic Compute Cloud (EC2) instances.

Whistleblower: Ubiquiti Breach “Catastrophic” — Krebs on Security

This is serious. If you have Ubiquiti equipment do change your credentials immediately and check for signs of compromise.

Adam says the attacker(s) had access to privileged credentials that were previously stored in the LastPass account of a Ubiquiti IT employee, and gained root administrator access to all Ubiquiti AWS accounts, including all S3 data buckets, all application logs, all databases, all user database credentials, and secrets required to forge single sign-on (SSO) cookies.

‘This is dangerous stuff’: Hacker increased chemical level at Oldsmar’s water system, sheriff says

This is why you should secure your endpoints, especially if you are operating a critical infrastructure. This seems to be one of those supervisory interface that is exposed over the internet. Thank goodness no real harm was done.

And this time, Gualtieri says, the hacker did more than just remote in. According to the sheriff, the hacker spent up to five minutes in the system and adjusted the amount of sodium hydroxide in the water from 100 parts per million to 11,100.

“This is obviously a significant and potentially dangerous increase. Sodium hydroxide, also known as lye, is the main ingredient in liquid drain cleaners,” Gualtieri added.

Autodesk Forge – Section hatches

Autodesk Forge has a nice feature known as section hatches. This feature fills out (or caps) parts of the model that is cut out by the section plane with a hatch pattern. You can see this in action below, when a z-plane cuts across the building:

The addition of hatches helps the viewer to see which parts of the model are cut out.

However, there is a problem with section hatches on some models, such as this:

The left part of the building is wrongly covered by the hatch and there are some weird triangulation problems on the right. This could happen when the meshes in the model is not 2-manifold.

Starting with Forge Viewer v7.35, there is a new option to turn off section hatches. It is located in the Configuration tab under Settings.

When you turn off section hatches, you still get the clipping, but without the potential artifacts:

You can also programmatically enable this behaviour by calling:

viewer.prefs.set(Autodesk.Viewing.Private.Prefs3D.DISPLAY_SECTION_HATCHES, false)

As a side benefit, performance is improved slightly with section hatching turned off.

If you are interested in the algorithms behind filling (or capping) of clipped mesh – though not necessarily the one implemented by Forge – you can refer to this and this.


Google discloses spearphishing targeting security researchers | SC Media

We are all familiar with spearphishing attacks against high value targets. But this is bold. A group of hackers are apparently targetting cyber security researchers, whose main job is to study them (the hackers) and their works. It’s like the thief stealing from the police. And the thief succeeded – in some cases.

Depending on how widespread the compromises were, it could potentially taint some research and defensive strategies that threat intelligence firms share with businesses and other organizations.

PostgreSQL on ARM-based AWS EC2 Instances: Is It Any Good? – Percona Database Performance Blog

ARM-based Graviton2 consistently outperforms Intel x86-based processors in PostgreSQL test by Percona, and it’s 25% cheaper. If your workload is not x86-specific there’s no reason not to switch.

The rise of ARM-based processor is gaining momentum and it seems like Intel is seriously playing catch-up here.

With the second gen of Graviton2 instances announced, we decided to take a look at the price/performance from the standpoint of running PostgreSQL.

AWS Fault Injection Simulator – Fully managed chaos engineering service – Amazon Web Services

Chaos engineering originated at Netflix with the creation of Chaos Monkey. The idea is that large-scale distributed systems require a different approach to test for failure, since there are so many moving parts. AWS is announcing a new service in 2021 that will help teams to implement chaos engineering to test their setup.

With Fault Injection Simulator, teams can quickly set up experiments using pre-built templates that generate the desired disruptions, such as server latency or database error.


FireEye Shares Details of Recent Cyber Attack, Actions to Protect Community

One of the world’s leading cyber security companies was breached, likely through a state-sponsored attack. One of the side effects of this attack is that FireEye’s own red-team tools will now be effectively “useless” for pentesting.

FireEye was recently attacked by a nation-state adversary and here are the actions we are taking to protect the community.

Consistent with a nation-state cyber-espionage effort, the attacker primarily sought information related to certain government customers. While the attacker was able to access some of our internal systems, at this point in our investigation, we have seen no evidence that the attacker exfiltrated data from our primary systems that store customer information from our incident response or consulting engagements, or the metadata collected by our products in our dynamic threat intelligence systems. If we discover that customer information was taken, we will contact them directly.
